I keep hearing that all of VI EQ is going to decay.
I can tell you now, if this is true, don't bother. You're wasting your time. V EQ is already far superior to what we used to have, and it is all we need against the weak hoards of mobs we have faced so far (and I'm sure that when VII ranked mobs are released, people will be able to kill them with ease in V EQ).
My suggestion? Stop all VI EQ development. Or remove the whole decaying system.
Nobody is going to want to spend a coupla gold on tech comps for armor/weapons/tools/jewelry/scales that will decay over time. Untech'd gear of VI will be inferior to tech'd gear of V (unless some astromical bonus is given to wearing/using these items).
